Re: [4diac-dev] Migrating forte to +11

Hi Jose,

It would be interesting to know which compilers are affected. I think it
makes a difference if it's a vendor-specific compiler with no upgrade
option or just older versions of well-known compilers.
I just want to open the discussion to know your opinions about if we
should start moving forte’s code to the standard +11 officially from the
next version or not.
Depending on the above question, I would go as far as moving straight to
C++17. It is the last small upgrade in the C++11 era and the core
features are well supported by the major compilers by now. Speaking of
Linux, there is probably no distribution anymore that is still in its
support life cycle and does not have a C++17 compiler.
Most importantly, C++17 would give us std::variant, which could simplify
the ANY type a lot and make it more type safe, while keeping its efficiency.
C++20, on the other hand, is definitely too new. Coroutines might be an
amazing way to simplify event queues and execution threads, but it will
probably take a long time until this appears in compilers for more
exotic platforms.
